Recreating this climbing system in Unity

Hello.

Ignoring the MS paint graphics and stolen music, how would one go about recreating this?

I tried using a hinge joint, but the “climbing tool” clips through walls. I’m really at a loss for what should be kinematic, what joint to use and what mass/gravity to put things at.

Any help is appreciated.

You could use a hinge joint to join the character and the hammer, then you need to get the mouse coordinates, and then applying a velocity or force to the hammer, in theory the hammer should move until it hits something, then the character should move, but this is just a theory
